Validator overview

The relative volume Validator calculates the time difference on two rows for each record:

Count ratio: Calculates the ratio between the number of rows in the source and the number of rows in the reference source.
Percentage ratio: Calculates the ratio between the percentage of rows in the source and the percentage of rows in the reference source that pass a given Filter criteria.

Reference source

Sensitivity

Higher sensitivity means that the accepted range of values is narrower, which identifies more anomalies. Conversely, lower sensitivity values imply a wider range of accepted values, which identifies fewer anomalies.
